Product Description

The RS-R T223D Down-Sus Lowering Springs deliver a refined performance upgrade for your Lexus GS300/GS400/GS430 (model years 1998-2005). With a front drop of approximately 20-25 mm and a rear drop of about 10-15 mm, this kit enhances stance and handling without compromising ride comfort. RS-R engineered these springs to resonate with the car's stock suspension geometry, delivering improved cornering response and reduced body roll while maintaining drivability.

Built from high-quality steel and coated for durability, the T223D springs are a direct-fit replacement for your vehicle's factory springs, enabling a straightforward swap without the need for additional shock absorber changes (unless your shocks are worn). These lowering springs are ideal for GS owners seeking performance and aesthetics - the lowered stance adds presence, and the tuned rates enhance driving dynamics.

When installed, the kit sets your Lexus GS at a more aggressive stance while preserving everyday usability. Alignment is recommended after installation to ensure proper suspension geometry and tire wear. Ensure that your vehicle matches the listed platform: 1998-2005 GS300, GS400 or GS430 (JZS160, RWD). Coverage beyond 2005 is not confirmed at time of listing.
